采用ZnO和环氧树脂机械搅拌制备ZnO/E-51复合涂料,通过真空袋压、室温固化成型,再通过化学刻蚀与表面修饰,在ZnO/E-51复合涂料上制备出超疏水表面。采用扫描电镜和动/静态接触角分析仪,表征表面的形貌和疏水性。结果表明化学刻蚀在复合涂料表面构建了具有微-纳米尺度二元粗糙结构;采用1%（质量分数）的硬脂酸修饰,可改变复合涂料表面微-纳米尺度二元粗糙结构,影响表面的疏水性能,当修饰时间为30min时,其表面与水的平均接触角最高达152.21°。
The ZnO/E-51 composite coating was prepared by vacuum bag pressure method after mechanical stirring the ZnO and epoxy resin,and then the superhydrophobic surface on ZnO/E-51 composite coating was obtained by chemical etching and surface modification.To characterize the surface morphology and superhydrophobicity,the scanning electron microscopy and dynamic/static contact angle analyzer were used.The results show that a micro-nanoscal binary rough structure has been fabricated on surface of ZnO/E-51 composite coating by chemical etching;through 1wt% stearic acid modification,the rough structure and superhydrophobic properties of surface can be changed.When the modification time is 30min,the maximum average contact angle of the surface with water is up to 152.21°.
